set_loop

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations present, the description carries the full burden and does add real behavioral context: it discloses the side effect (writes loop state) and states the change occurs 'in one undo step', which is genuinely useful for a mutation tool. It stops short of noting permissions, error behavior, or what the call returns.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core action, then side effects, example, and edge case in short labeled fragments. No filler; slightly choppy but every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-boolean mutation tool with no annotations and no output schema, the description covers the action, the side effect, undo granularity, an example, and the type constraint. Return value and failure behavior are unaddressed, but not critical here.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the schema field 'enabled' has no prose, but it is a lone boolean whose meaning is stated in the body ('Enable or disable'). The example set_loop(True) and the edge case 'only a boolean value is accepted' add a little beyond the type declaration, which is enough to offset the weak coverage but not more.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Enable or disable') and resource ('the Arrangement loop'), so the agent knows exactly what changes. It does not explicitly differentiate itself from siblings like get_loop_settings, set_loop_start, or set_loop_length, which is the only thing keeping this from a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the clear verb+resource pairing, but there is no explicit statement of when to reach for this versus get_loop_settings (read) or set_loop_start/set_loop_length (boundary edits). No prerequisites or exclusions are given, leaving the routing to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
